I still had live larvae in the stems after -10 degrees in January 2021 with no snow cover. Continental European crops will be subjected to colder temperatures, so my guess is a no.

I thought when i dissected a few stems that several were dead- perhaps it's just wishful thinking!

Crusiferous and striped flea beetle They will chew leaves off and if the surface is crusted and few plants have emerged they will chew off below the crusted soil.

Some even canola snow canola. They have brought it apon them selves

Couldn’t really say with any degree of accuracy, I’ve had no problems but I’ve never really had them too bad. The seed dressing are next to pointless and not worth the money but you can’t get seed without them. I’ll ask my agronomist. He’s been in the trade for twenty years so should know.
